SETH (Scintiallation Event Triggering Hodoscope)

A new team of students from Kiel University proposes the instrument SETH and plans to apply to the next cycle of the BEXUS programme. SETH is the Egyptian God of CHAOS.

We are CHAOS!

CHAOS is a particle telescope to measure Galactic Cosmic Rays developed by a team of students from the Department of Extraterrestrial Physics at Kiel University. To perform these measurements a combination of multiple Solid State Detectors (SSDs) and a Bismuth Germanium Oxide (BGO) scintillator is used to measure the energy deposition of the particles. The use of an additional Cherenkov aerogel scintillator allows to separate between electrons and protons. CHAOS was part of the stratospheric balloon mission BEXUS 35 in fall 2024.

On our website you can find all information regarding SETH, CHAOS and past contributions of Kiel University to the BEXUS programme. Check out our blog to stay updated on all our activities.

The REXUS/BEXUS programme is realised under a bilateral Agency Agreement between the German Aerospace Center (DLR) and the Swedish National Space Agency (SNSA). The Swedish share of the payload has been made available to students from other European countries through a collaboration with the European Space Agency (ESA). EuroLaunch, a cooperation between the Swedish Space Corporation (SSC) and the Mobile Rocket Base (MORABA) of DLR, is responsible for the campaign management and operations of the launch vehicles. Experts from DLR, SSC, ZARM and ESA provide technical support to the student teams throughout the project. REXUS and BEXUS are launched from SSC, Esrange Space Center in northern Sweden.
